Title: Electrophotographic printer
Inventor: IIDA YUJIRO
IPC: G03G15/20
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent the reverse curling of a recording paper and to carry it to the side of an ejecting mechanism part by arranging a heating roller and a backup roller, in a position for carrying the recording paper, while winding it on the periphery of the heating roller. SOLUTION: When a thin recording paper 5 to which toner is stuck is carried to between the heating roller 31 and the backup roller 32 in a fixing part 30, the toner is fixed by the heating of the heating roller 31, to complete the printing of the recording paper 5. In such a case, the heating roller 31 and the backup roller 32 are arranged in a part lower than the ejecting mechanism part, so that the recording paper 5 is guided to a carrying roller and a pinch roller, while being wound on the periphery of the heating roller 31, in a state where a printing surface 5a faces upward. Thus, when the recording paper 5 is wound on the periphery of the heating roller 31, the reverse curling, that is, the curling in a direction opposite to that of the printing surface 5a is prevented so that a flat recording paper 5 is guided to the carrying roller.

Title: Descaling method for continuous casting steel billet
Inventor: OOTSUBO TOSHINORI
IPC: B21B1/46
Filed: 1988-10-28
Abstract: PURPOSE:To prevent generating a defect caused by scales by injecting high pressure water of a specified pressure on the surface of the billet through the descaling apparatus on a coveyer belt. CONSTITUTION:The steel billet is conveyed through a machine end 2 of the continuous casting equipment 1 to a heating furnace 3, is passed through a rough rolling mill 5 and finish rolling mill 6 of a hot rolling mill 4. Between the machine end 2 and heating furnace 3, the descaling apparatus 10 is provided. Through this descaling apparatus, the high pressure water of delivery pressure >=10kg/cm<2> is injected on the surface of the obverse and reverse of the moving steel billet. By this method, the hematite layer, magnetite layer and wsutite layer on the surface of the steel billet are completely exhausted and the fayalite layer is nearly removed. Then, up to the heating furnace 3, the scale is generated by air oxidation, further, through heating oxidation in the heating furnace 3, scale is generated, but in this stage, the generation of the fayalite layer is small, as a result, since generating pores and cracks in the wsutite is suppressed, peelable scales account for the majority. Therefore, the scales are mearly completely removed by the descaling apparatus 7.

Inventor: WATANABE YOSHIJIROU
IPC: F42B3/10
Filed: 1990-10-09
Abstract: PURPOSE:To reliably prevent any erroneous operation by providing a noise removing means on a signal line between an acceleration sensor and a threshold- value circuit which calculates, on the basis of the output therefrom, an anticipated value such as the deviation or speed of a passenger relative to his seat after the lapse of a specified time period, and which generates a trigger signal when that value exceeds the threshold value. CONSTITUTION:By integrating the output a (t) of an acceleration sensor 1 at the time of a vehicle collision by first and second incomplete-integration circuits 2, 3, the amount deviated of a passenger's head is calculated. The integration outputs are weighted by coefficient circuits 5, 4, whereby the amount deviated in a length of time t1 is obtained. The outputs of these coefficient circuits 5, 4 are subjected to removal of the noises by movement-averager circuits 6, 7, the outputs of which are added together in an adder circuit 8 to determine an anticipated position value of a passenger's head after the lapse of a time length from the present time t to a future time point t1. And the anticipated position value is supplied to a comparison circuit 9. When this value has exceeded a threshold value, an ignition current is supplied to an ignitor device 11 to cause an operating of the air bag, thereby protecting the passenger.

Title: Image fixation device
Inventor: TAKEMOTO MITSUTOSHI
IPC: H05B3/00
Filed: 1990-10-09
Abstract: PURPOSE:To reduce the cost and to prevent a pressure belt from being damaged by providing heat sources which heat a heat roller, a temperature detecting means which is arranged nearby the heat roller, and a control means which brings the plural heat sources under the temperature control of the temperature detecting means. CONSTITUTION:The temperature of the heat roller 18 rises and falls within constant temperature width as a heater 24 is turned ON and OFF, but a fixation part driving system is turned ON to rotate the heat roller 18 and a pressure belt 19, so the temperature of the pressure belt 19 has transition similar to that of the heat roller 18 by receiving the heat of the heat roller 18. The temperature of the heater 27 of a pressure belt roller 26 never becomes higher than the temperature of the heater 24 of the heat roller 18 because of its wattage and a state wherein the heater 24 of the heat roller 18 is OFF and the heater 27 of the pressure belt roller 26 is ON is never entered. Consequently, only one temperature detecting means, i.e. a thermistor 28 is installed adjacent to the heat roller 18. Consequently, the cost of the fixation device is reducible and the damaging of the pressure belt 19 due to the installation of the temperature detecting means is eliminated.

Abstract: PURPOSE:To regularly arrange a random logic gate section to be formed in logic LSI without deteriorating the characteristic of the circuit, by trying not to lengthen the length of power and ground wiring to be laid out in each logic gate, and making the number of wirings wirable in the longitudinal direction the same as that wirable in the transverse direction. CONSTITUTION:Concerning to power supply to a control section, main power lines 25 and 27 and main grounding lines 26 and 28 are laid out by diffusion layer wiring or upper layer wiring in a direction parallel to a ROM 23 and an arithmetic circuit 24. In a direction perpendicular to these main power and grounding lines, logic gate anays 29 and 30 are formed, and the power lines 31 and 33 and the grounding lines 32 and 34 of the gate arrays are formed by lower layer wiring, and connected to the main power lines and the main grounding lines respectively. This constitution makes it possible to regulate the length of the power and grounding line of the gate arrays by the mutual intervals between the main power and grounding lines. The control section becomes longer in the transverse direction, in parallel with the ROM 23 and the arithmetic circuit 24. As a result, the number of wirings 35 between the gate arrays is apporoximately equal to that of wirings 36 on the gate arrays.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a cooling device by preventing the service life of a horizontal rotary compressor from becoming shorter by restricting the liquid refrigerant sucking amount of the compressor from a lubricating mechanism section at a low temperature. SOLUTION: A cooling device uses hydrofluorocarbons as refrigerants 12A and 12B and oil having no mutual solubility with the refrigerants as the lubricating oil 11 of a horizontal rotary compressor 5 and is provided with a heater control means which controls the energization of a belt-like heater 17 wound around the barrel section of the central shell of the compressor 5 in the longitudinal direction, an outside air temperature detecting means which detects the temperature of the outside air, and an arithmetic processing section which causes the heater control means to energize the heater 17 when the outside temperature detected by the outside air temperature detecting means is lower than a prescribed value. Therefore, the energy consumption of the cooling device can be reduced and the compressor 5 does not suck the liquid refrigerants from a lubricating mechanism section. Therefore, the service life of the compressor 5 is prevented from becoming shorter and the reliability of the cooling device can be improved.
